Developers & API

Hey fellow Strava enthusiasts! I've been an avid user of Strava for quite some time now, and I must say, it's an incredible platform for tracking and sharing my athletic endeavors. Recently, I've been exploring the capabilities of the Strava API and wondering if it's currently possible to upload media files, such as images or videos, to an activity using its ID. I haven't been able to find any specific information or documentation regarding this capability in the Strava API. I was wondering maybe it's possible even if it's not documented as its the case for getting pictures of an activity [https://www.strava.com/api/v3/activities/{id}/photos?size=X]. That's why I'm turning to the Strava community and API developers for insights. If any of you have experience with the Strava API or know whether it's currently possible to upload media files to activities using their I

Dear all, I’m currently setting up a webhook endpoint for my Strava app, but Strava cannot verify or access my HTTPS callback URL.Details: Endpoint: https://chaytructuyenapi.thaco.com.vn/api/strava/callback Server: Windows Server (IIS) SSL Certificate: Wildcard certificate for *.thaco.com.vn Issuer: Sectigo Public Server Authentication CA DV R36 Valid: 09 Sep 2025 – 08 Oct 2026  When testing with openssl s_client -connect chaytructuyenapi.thaco.com.vn:443 -showcerts, I get:verify error:num=20:unable to get local issuer certificate Browsers show the site as secure, but Strava’s webhook callback still fails.I suspect the intermediate certificate (Sectigo R36 chain) might not be correct

I notice if I add an ampersand (&) or sometimes less than/greater than signs (< and >) to the name of my activity when uploading a gpx file via the API, I will get back the error below, even though the same exact gpx file uploads fine with another activity name. I’ve tried escaping and encoding, but can’t make it work.{  ...  error: `Improperly formatted data. <a href="https://support.strava.com/hc/articles/216917967-Uploading-poorly-formatted-GPS-files" 'target="_blank">More Information</a>.`,  status: 'There was an error processing your activity.',  activity_id: null}

Since today I wasn't able to share my activities to my instagram story. It only allows me to share the link of thr activity.

We are in the process of migrating our staging/test application to a new account and would like to increase its athlete capacity.Our production app was reviewed some time ago and is functioning as expected. Additionally, the previous staging/test applications were also reviewed and granted increased athlete capacity (999).According to the documentation, we're advised not to submit the review form for staging or test apps, which makes the process unclear—especially since the production app has already been reviewed.Could you please clarify how we can increase the athlete capacity for the new staging app under these circumstances?

Hi All..  I am in the early stages of creating an app to use the Strava API - I’ve got a development background so don’t see any technical issues from the API documentation.The App will NOT show a user any other user’s data apart from their own.  It will do some analysis on each activity detail (not AI or machine learning) and give some feedback - for example: “that ride/segment was particularly fast as there was hurricane speed winds behind you which gave you a PB”However, Strava’s API agreement states:No Strava Data shall remain in your cache longer than seven days. If your Developer Applications check for a resource (e.g., a segment) and that resource is no longer available from Strava, you shall remove it from your cache immediately regardless of how frequently you refresh your cache. Except for such limited caching, your Developer Applications are prohibited from storing any Strava Data or providing or displaying such data or any associated ser

I’m encountering an issue with the paging parameter at the endpoint for listing club activities.I am currently running a sports challenge that uses Strava clubs to track participants' activities. To limit the activities, I retrieve all activities using the after parameter. Today, I had more than 200 activities. When I requested the activities using the page parameter set to 2, I always received the same result. It doesn’t matter if I send page=2, page=3, or another value—I always get the same data. Why?Thanks!

I use a Fenix 6S and upload activities to Strava with an Android phone.When I save an outdoor row without making any edits it saves correctly showing the pace/500m BUT as soon as I make any changes for instance to the title of the activity it switches to show Time, Distance and Calories instead which is really frustrating as it’s useless information.  I think this is part of an earlier bug with QE where it was saving the row as ‘workout’.My friend uses an iPhone and does not have this problem  as the screen shot below shows.   Links to activities are below the screenshot. https://www.strava.com/activities/15855718821   Incorrect data displayed

I recently had my athlete capacity increase request approved.At first time, the athletes allows is 999.Currently, I have 989 connected athletes.I emailed the Strava team to request a higher limit and was advised to submit a new request.After submitting again, the request was approved — but the capacity still shows only 999 athletes.Could someone from Strava please confirm if this is expected behavior? If a full increase is not possible right now, would it at least be possible to raise the limit slightly (for example, beyond 999) so our users are not blocked?

I have built and tested an app to monitor rowing performance data for my club. However, the app is limited to 1 athlete (i.e. me as. the test subject). I can’t find a link/button which would let me apply for “production status” for my app so that multiple users can use it. Any ideas?

saya cahaya mirte ingin meminta pengembalian dana, saya tidak ingin atau tidak berniat untuk berlangganan setelah melakukan uji coba gratis. Tidak ada penawaran atau pun notifikasi yang di berikan pihak strava untuk melanjutkan berlangganan atau menghetikannya, namun tiba tiba saldo saya langsung berkurang yakni sebesar 609.000. Saya disini memohon dengan sangat untuk pengembalian dana ini, uang tersebut seharusnya saya gunakan untuk keperluan yang lainnya.

For some reason for most of the day I cant publish in any clubs. When I tap publish it doesn't even let what I wrote publish. It's a weird and frustrating glitch that you guys could look into please and thank you

So after following 70 people by accident back to back strava won't let me follow anyone anymore everytime I tap follow it says an error encounterd with the strava servers. And the weird thing it i only had a total of 123 following people. Can you please respond and tell me how to fix this it's been going on for nearly 2 days were I corn follow and one please and thank you.

I’m building a personal comment automation tool using the Strava API.The app is for personal use only, designed to automatically post my own annual mileage data as a comment on my activities. I have confirmed that my access token includes “ [scope] => read,activity:write,activity:read_all,profile:write,profile:read_all,read_all”, and I am attempting to post a short comment to my own activity using the endpoint:`POST /api/v3/activities/{activity_id}/comments` However, I consistently receive a `401 Authorization Error`, and the response does not include any explanation or error details. Could anyone confirm whether comment posting via API is allowed for my app, or if there are any restrictions I should be aware of?

Hi,I´m using `${STRAVA_API_URL}/clubs/${clubId}/group_events` where const STRAVA_API_URL = "https://www.strava.com/api/v3";It seems that the id of some of the club events is obfuscated and the last digits are replaced with zeroes, so that e.g. 3393591506183906380 becomes 3393591506183906300 in the result JSON.Why is this error introduced? 

I am trying to make a personal widget that shows my latest activity in the way that strava does in the feed. I am almost there now but I just can’t get the map to show the route line and I believe this is an issue with the polyline summary. Below is the code that I an using in scriptable, any ideas where I am going wrong?  // -------------------------// CONFIGURATION// -------------------------const clientId = “My Client ID";const clientSecret = “My Client Secret";const refreshToken = “My Refresh Token";const googleApiKey = “My Google API";  // <-- paste your key hereconst athleteName = "Jess Langdon";const profilePicUrl = “My Profile Pic URL";const typeIcons = {  Run: "https://img.icons8.com/ios-filled/50/808080/running.png",  Ride: "https://img.icons8.com/ios-filled/50/808080/cycling-road.png",  Swim: "https://img.icons8.com/ios-filled/50/808080/swimming.png",  Hike: "https://im

We have reached the 999 Athlete limit and have tried contacting support, resubmitting the app for verification, and we have not heard back on how to increase these limits.Is there a separate contact form or method to get this number increased? I have sent mail and filled forms still no response from Strava 

 HiI'm building a system for myself and a group of users. I'm trying to get the info from Strava and send it to Health Connect (Google) and HealthKit (Apple Health), lets call them HealthApps refering to both of them. All activities are Public. But I'm having some problems: 1. Rouvy and many others didn't send data to Health Connect. So I plan to send example from Rouvy to Strava, then from Strava to Google Fit, then Google Fit to Health Connect. But from Strava it breaks and didn't get sended to Google Fit (which is active as "Other Services").First I suspect it was because it was created by a 3th party app. Then I create an activity direcrly from Strava and again it never gets to Google Fit.As a proof other direct activities from Garmin went out to Google Health and to Google Fit correct. So problem is not in Google Fit.I need to solve it. Please help me, I need to send ALL activities that start or not in Strava... 2.

I don’t see any endpoint, but it can’t hurt to ask: is there an API method to add a comment (not changing the description) to an activity?

Hello! I’m a Strava subscriber who organizes a local cycling club. I’ve created a club for it within Strava, but I want to push each week’s ride activity into Strava via the API. Is it possible to add write methods to the club activities API so each week I can have another system push that data to Strava? Thanks!

When my app attempts to update an athlete’s activity (title, description), the API is returning an HTML page saying that Strava is temporarily unavailable. This is accompanied with a 503 error. Two things worth noting are:The activity is actually updated, so that seems to rule out any authentication/authorization issues. As of now, the status page at strava.status.com shows all systems are online. Is anyone else experiencing this? And is this really a Strava issue or might there be something I need to change on my end?Here’s the response text I’ve been receiving:<!DOCTYPE html><html><head> <title>Strava is temporarily unavailable</title> <meta http-equiv='Content-Type' content='text/html; charset=utf-8'> <meta name='viewport' content='width=device-width, initial-scale=1' /> <meta name='robots' content='noindex' />

Since today, most of my POST requests to the /uploads API are failing with HTTP 413 (Payload Too Large).I did some additional tests and it seems that files bigger than 1MB are being rejected - unfortunately most of my (TCX) files are larger than that.This issue started to occur today (28.08.2025) after 13:15 UTC. All uploads before were successfull. All uploads afterwards are failing

I know scraping is frowned upon but is it fair game to source the public athletes endpoint (e.g. https://www.strava.com/athletes/{id}) which is reachable without a login and is not explicitly forbidden by the robots.txt for athlete image links and other stuff to use in a Strava API application? Sorry if this happens to be a duplicate question. Have a nice day!

Hi I was just wondering if there was an endpoint(s) to access data behind the public global heat map?

I’m looking to incorporate the Global Heatmap data into recreation and conservation planning efforts in USA.  Is this possible?  Is there someone I could speak with to discuss it?
